8. What repairs have been done to the dam? A major storm event destroyed the lock, gatehouse and did major damage to the west abutment of the dam in 1913. The dam was then repaired in 1925 (after sufficient funds were raised) with the addition of a concrete retaining wall where the lock was previously located, replacement of the west abutment and the addition of two 3-foot by 5-foot gates located in the gatehouse bulkhead.
9. Reason(s) for Removal:
a) aesthetic enhancement -
b) fish and wildlife habitat improvement - X
c) cost savings____
d) community revitalization - X
e) public safety hazard
f) water quality improvement - X
g) recreational improvement - X
h) alternative to dam ____
Notes:
(1) A bypass is being constructed adjacent to the Kent Dam by removal of the adjacent retaining wall/sluice gate structures. This will allow the existing stone arch dam and associated crest to remain in-place with a new recirculating waterfall feature to be added during the Cuyahoga River Restoration Project (CRRP) construction (which began in Spring 2003).
(2) The main driver of this project was OEPA's Middle Cuyahoga River TMDL study which identified water quality and habitat problems.
10. Project Sponsor (who initiated project): City of Kent
11. Dam Removal Funding Sources:
a) federal - X (indirectly through state)
b) state - X
c) local governmental agencies - X
d) other (please explain) ____________________
12. Cost of Dam Removal: $3.7M (estimated construction cost for entire project). Rebuilding of West Lock Wall, removal of East Lock Wall and demolition of retaining wall/sluice gate demolition were estimated at approximately $500K
